更改 UISegmentedControl 的字体大小

谁能告诉我如何更改字体类型和大小UISegmentedControl?

我遇到了同样的问题。此代码设置整个分段控件的字体大小。类似的东西可能适用于设置字体类型。请注意，此功能仅适用于 iOS5+

Obj C:

UIFont *font = [UIFont boldSystemFontOfSize:12.0f];
NSDictionary *attributes = [NSDictionary dictionaryWithObject:font
                                                       forKey:NSFontAttributeName];
[segmentedControl setTitleTextAttributes:attributes 
                                forState:UIControlStateNormal];

EDIT: UITextAttributeFont已被弃用 - 使用NSFontAttributeName反而。

编辑#2：对于 Swift 4NSFontAttributeName已更改为NSAttributedStringKey.font.

Swift 5:

let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSAttributedString.Key.font: font], for: .normal)

Swift 4:

let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSAttributedStringKey.font: font],
                                        for: .normal)

Swift 3:

let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
                                        for: .normal)

斯威夫特2.2:

let font = UIFont.systemFontOfSize(16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font], 
    forState: UIControlState.Normal)
